All of the old threads are still around, but I have no idea what that would have linked to. AFAIK, all of the old thread ids were imported exactly as they were before, and so there should be a thread 15317, but I don't see it. Maybe an upgrade to the forum software messed this all up without me knowing.

FWIW: The URLs by default are thread-ID.html, but you can also use the form showthread.php?tid=ID. Apparently the older t=ID does not work which could be fixed with some modrewrite.

That was some old pong thing that hairball was messing with. I wound up writing a different implementation for him, which uses my timing algorithm which I learned from ThemsAllTook's timing tutorial. That should be here at iDG too, but I don't have a link handy for it.
